Regarding your question, it is forbidden for vehicles equipped with automatic transmission to slide in neutral. Only when the vehicle is stopped can the gear be shifted to N gear. Switching to N gear when an automatic transmission vehicle is driving will cause serious damage to the gearbox, thus reducing the service life of the gearbox. Therefore, you must not put the gear handle in the N position during driving, because the internal parts of the automatic transmission need lubrication. When the gear is in the N position during driving, the oil pump cannot supply oil normally, which will cause serious damage to the internal parts of the gearbox. S gear is a sport mode. In this mode, the vehicle is the most dynamic at first. Usually it is ok to keep the S gear, but the fuel consumption of the engine will be higher than when the D gear is engaged. I hope my answer is helpful to you.
